v0.2.8

P0 fixes: CSP-clean verify page (no inline handlers), samples command, page hash with placeholder recipe.

v0.2.7

PyPI 0.2.7, npm 0.2.7.

Fixes:

• JS: 3e-05 now matches Python (was 3.0000000000000004e-05)
• verify.html: footer hash verifiable via blanked-field scheme

verify.html hash scheme: replace the 64-char hash in the footer with
PAGE_HASH_PLACEHOLDER_64CHARS_PADDING_XXXXXXXXXXXXXXXXXXXXXXXXXX,
SHA-256 the result, compare with the footer hash.

v0.2.6

PyPI 0.2.6, npm 0.2.6. Full v03 check catalog in JS. Release assets: verify.html + SHA256SUMS.

v0.2.5

qlm-measure 0.2.5

Published: PyPI 0.2.5, npm 0.2.5

Assets

• verify.html — single-file browser verifier (no network, no install)
• SHA256SUMS — hash of verify.html for "verify the verifier"

Changes since 0.2.4

• Entry-hash vectors: all 10 embed the full entry (executable in both languages)
• Canonicalization vectors: float_one and unicode_keys labeled known_limit
• CLI dispatches schema 0.3 records with correct check catalog
• JS verifier: level1 accounting fixed (SCHEMA.TYPES/REQUIRED separation)
• JS loader accepts schema 0.3 records
• Verify page: CSP uses script hash (no unsafe-inline), version in footer
• Samples flattened to samples/

Known 0.2 limits (documented in schema/canonicalization.md)

• Integer-valued float inside event objects (score: 1.0 vs 1)
• JS-written integer weight verified by Python (1 vs 1.0)
• Both fixed in schema 0.3 via RFC 8785
